0.26.0

Standard Library

• Added arguments for upload and download progress to Http.send.
• Added FormData variant to Http.ResponseBody.
• Added FormData.getFile and FormData.getString functions.
• Added File.fromUrl function.
• Added Regexp.exec function.

Exporting Entities

The build command now takes any number of --export arguments which allows exporting entities from the final bundle.

Functions and constants can be exported from modules, variant constructors from types and components. Components are exported in a way that they can be used easily.

Here is a minimal example:

component Greeter {
  property name : String = ""

  fun render {
    "Hello #{name}!"
  }
}

mint build --export Greeter

import { Greeter } from `index.js`;

// Render the component into a DOM element.
Main.render(document.querySelector('div'), { name: "Joe" })
